Help with your Marklin Locomotive - Excess Oil (DCM Motor cleaning)

[@christianness8983]

Oh my word thank you! My locomotive was having issues just today and this has to be the right fix. I accidentally over oiled it and it's been running for a number of years now, sometimes eight + hours at a time.

Glad it helped!

Thank you very much, very interesting in case an error occurs

Excellent video, thank you!!!

Missing one step. After cleaning out the mesh i’ll polish this part with grade 1500 sandpaper until it’s clean. Then reclean the groves This by using a Dremel on the gear site does the job

A great tutorial, thank you! I am looking for help regarding when the spring wire breaks that holds the brushes in place. I have two loco's with this issue. Any help is appreciated!

[@ajckids]

You can buy the motor covers as spare replacement parts. That would be imo the easiest way to fix that issue!

Thanks AJK; have just been looking at 'tune-up' of some 'less than satisfying' stuff - looking at this was like coming home again. I notice you did not re oil?? Also, does removing the armature compromise the magnet power. I believe where a stator magnet is magnetised with the armature in place there is a question mark. Upgrading motors to 5 slot rotors is a great way to improve performance. I was told not all cylindrical commutator motors can be so modified. Is this true? Could talk Marklin all day; better shut-up.

[@ajckids]

In most cases it would be good to reapply a bit of oil. But many folks actually oil too much. And that in turn just gives residue and dust and dirt a good place to stick to. You can remove the armature without concerns for magnet power. There are a (very) few Marklin models where upgrading the DCM motor to a 5-pole can give you some space challenges. The upgraded motor is a fraction thicker. In those cases you can always opt for the 3-pole DC magnet, and leave the motor as a 3-pole motor.

Does the armature supposed to spin freely by hand?

[@ajckids]

Yes. When it is just the armature and the magnet, the armature may move and stick to the magnet. When the motor is assembled, you most likely will feel friction of the gears (and magnet) and the wheels will not spin freely. But you can definitely move the wheels.

Tell what lok that is, thx!

Hi Rune, This is a 39378 Class 101. We did not mention it because the steps will be very similar to many Electric and Diesel model Marklin locomotives with truck mounted DCM motors. When it comes to steam locomotives, the procedure could be even easier, since you will not have to lift up the truck assembly to get to the motor plate.
